What only OpenNan Voice does
Meeting apps translate only inside their own calls. Voice changers change how you sound but don't translate. OpenNan Voice does both, in any app.

Voice Translator: questions
What does Voice Translator cost?
$0.0206 a minute for the speech you send and $0.066 a minute for the voice it speaks back, paid from your OpenNan balance and billed by the second. Every account gets one free 3-minute trial, shared by the app and the API.
How do I call it?
Create a session through OpenNan, then connect to the WebSocket it returns with its short-lived ticket.
Am I charged when something fails?
No. A step that fails is not charged, and the reason is shown in plain words.
Can I use someone else's voice?
No. You can clone only your own voice, with a recording of you reading a consent sentence we give you. Voices are never shared between accounts.
Can my AI agent use it?
Yes, over the API. Have it read https://api.opennan.com/llms.txt to learn how.
